数组类 - 错误：无法将参数从'double'转换为'int'

Question

我早前向社区咨询过这个程序，但我遇到了最后一个问题，并且在互联网上进行了快速搜索，结果显示它是常见的一个。

以下其次是我的构建输出我的代码

Grader.cpp

#include <iostream> 
#define MAXSIZE 100 
#include "Grader.h" 

Grader::Grader(){ 
my_Values [MAXSIZE] = 0; 
my_ValuesSeenSoFar = 0; 
} 

void Grader::addScore(int score){ 
if(my_ValuesSeenSoFar < MAXSIZE) 
    my_Values[my_ValuesSeenSoFar++] = score; 
} 
void Grader::addScores(int scores[], int size){ 
    for(int i=0; (i < size) && (my_ValuesSeenSoFar < MAXSIZE) ; i++) 
     my_Values[my_ValuesSeenSoFar++] = scores[i]; 
} 
void Grader::clear(){ 
    for(int i=0; i < MAXSIZE ; i++) 
     my_Values[i] = 0; 

} 

int Grader::findBiggest() const{ 

    int max = my_Values[0]; 
    for(int i=1; i < my_ValuesSeenSoFar ; i++) 
    { 
     if(my_Values[i] > max) 
      max = my_Values[i]; 
    } 
    return max; 
} 
int Grader::findSmallest() const{ 
    int min = my_Values[0]; 
    for(int i=1; i < my_ValuesSeenSoFar ; i++) 
    { 
     if(my_Values[i] < min) 
      min = my_Values[i]; 
    } 
    return min; 
} 

Driver.cpp

#include <iostream> 
#include "Grader.h" 
using namespace std; 
int main() 
{ 
Grader g; 
double d[5]= {99,70,85,93,84}; 
double e[4]= {100,81,60,91}; 

g.addScore(75); 
g.addScore(82); 
g.addScores(d, 5); 

cout << "Best Score = " << g.findBiggest() << endl; 
/// should give value 99 
cout << "Worst Score = " << g.findSmallest() << endl; 
/// should give value 70 
g.clear(); 

g.addScore(50); 
g.addScore(74); 
g.addScores(e, 4); 

cout << "Best Score = " << g.findBiggest() << endl; 
/// should give value 100 
cout << "Worst Score = " << g.findSmallest() << endl; 
/// should give value 50 
} 

而且我的错误输出如下

任何想法？

Answer 1

double d[5]= {99,70,85,93,84}; 
double e[4]= {100,81,60,91}; 

您d/e被定义为双然而，Grader::addScores只需要整型。

void Grader::addScores(int scores[], int size) 
g.addScores(e, 4); 

如果你不是说做d/e双，tchange他们为int类型：

int d[5]= {99,70,85,93,84}; 
int e[4]= {100,81,60,91}; 

Answer 2

double d[5]= {99,70,85,93,84}; 
double e[4]= {100,81,60,91}; 

使它成为int。
